Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533726, here are decompositions:

5 + 31533721 = 31533726
19 + 31533707 = 31533726
67 + 31533659 = 31533726
89 + 31533637 = 31533726
113 + 31533613 = 31533726
127 + 31533599 = 31533726
139 + 31533587 = 31533726
163 + 31533563 = 31533726

Showing the first eight; more decompositions exist.
